Hi Dinesh,
The error is almost certainly a mistake in the changes to the RegistrationDAO. Double-check your modifications there and also ensure that the new field has been added to your database, not just the OJS code. Some knowledge of SQL is necessary for this kind of change -- but it should be a fairly quick change if you can get help from somebody on hand.
